Nadine bought two shirts and three pairs of pants at a back-to-school sale. The shirts cost $16.50 each and the pants cost $19.95 each, tax included. If she paid with a $100 bill, how much change should she receive?

First you would make an equation.

S = shirts; P = pants

2 (s) + 3 (p) = 100

you would inout how much each item costed. 2 (16.50) + 3 (19.95) = 100

2 (16.50) = $33 and 3 (19.95) = $59.85

you would add your answers together $33+$59.85 = $92.85

to find out the amount of change left over from a $100 you would subtract the total cost from 100.

$100-$92.85 = $7.15

your final answer would be $7.15
